THIS IS A TEST...........THIS IS A TEST...........

THIS IS A TEST...........

THIS IS A TEST...........
A TEST_BLOG to exercise the limits on the code block in the blog description Editor.

There seems to be a limit on the size of the code block!4

THIS SEEMS TO CAUSE THE BLOG TO GO INTO MODERATION

WHY!!!!

Code blocks are created from the insert/code option.

HERE IS AN EXAMPLE OF HOW IT LOOKS PUBLISHED.

CODE- MKR_LoRa_Sender_E2.ino

/*

The packet will be sent

BLOG#5 Testing Part 2 (Case Enclosure Reliability Monitor)

Test#2 - Enclosure 155H2GYCL Test Design

For this Test, I purchased two Grove Sensors from Seeed and used two of sensors from the supplied Grove starter Kit.
This is my 2nd Test, using a Hammond Enclosure. I will be testing the Ingress Protection Rating: of IP68 on the enclosure model:155H2CYCL.

I also purchased the Arduino MKR Connector Carrier from the Arduino Store, for this test

I'm utilizing the provided Arduino MKR WAN 1300 boards supplied by Hammond Manufacturing for the Design Challenge: Just Encase.

TEST# 2 - Measure the Environment within the Waterproof Enclosure 1554H2GYCL

Description
- For this Test, I purchased two Grove Sensors from Seeed and used two of sensors from the supplied Grove starter Kit.
- I also purchased the Arduino MKR Connector Carrier from the Arduino Store. This is used to attach the sender MKR1 from the previous test and attach the groove sensor connectors.
- The List of components used in this test:
  - Arduino MKR Connector Carrier
    - The Arduino MKR CONNECTOR CARRIER provides Seeed Studio's Grove connectors to your MKR board.
    - This shield can allow you to build applications with different IoT connectivity's by simply changing the MKR board and with almost no changes to the code.
    - BUY it from the Arduino Store
  - Grove - Dust Sensor（PPD42NS）SKU 101020012
    - This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration.
    - The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in a given time unit. LPO time is proportional to PM concentration. This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.
    - Buy it from Seeed
  - Grove - Water Sensor SKU 101020018
    - Grove - Water Sensor detects the presence of water using exposed PCB traces.
    - The sensor is made up of interlaced traces of Ground and Sensor signals.
    - The sensor traces are weakly pulled up using 1 MΩ resistor.
    - The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace.
  - USB Ruggedized Charger for Power
    - The AdventureMax 10000mAh by MyCharge
    - splash resistant
    - drop resistant
    - dirt-proof
    - II had this charger lying around the house. I decided to use it to power the MKR WAN 1300.
  - Grove - Starter Kit Sensors
    - Grove - LCD RGB Backlight
      - The Grove - LCD RGB Backlight supports text display, using user-defined characters. It enables you to set the backlight color, using the simple and concise Grove interface. It uses I2C as the communication method with your Arduino.
      - This is a 16x2 LCD screen.
      - It is capable of displaying two rows of sixteen-character texts, supporting languages such as English and Japanese.
    - Grove – Temperature Sensor
      - the Grove - Temperature Sensor uses a thermistor which returns the ambient temperature.
      - The board then converts this voltage value measured by an analog input pin to a temperature.
      - The operating range is -40 to 125 degrees Celsius.
      - Wiki] Grove - Temperature Sensor

Wiring Diagram
- All the sensors mentioned in the previous section are connected to the Arduino Connector Carrier with a Groove Cable connected to the designated connectors.
- One end of the cable is attached to the Grove sensor and the other to the Grove connector on the Carrier.
  - The LCD Display is attached to the TWI ()I2C) connector
  - The TEMPRATURE sensor is attached to the analog A0 connector.
  - The DUST sensor is attached to the digital D4 connector
  - The WATER sensor is attached to the digital D2 connector
- The Arduino MKRWAN 1300 Is attached to the Connector Carrier in the relation shown below
  - For POWER, the AdventureMax 10000mAh is attached to the USB connector on the MKRWAN 1300
  - The LoRa Antenna is attached to the antenna connector on the MKRWAN 1300

Three MCU"s, Three Sketches to get the the data through.
The next Three section will describe the 3 sketches used to get the data thru and onto the Arduino IoT cloud.

LoRa SENDER - MKR_LoRa_Sender_E2.ino on MKR1

This sketch is Uploaded to the MKR1 board in my design.
This Sketch, will be used to transmit LoRaWAN packets to the MKR2 LoRa Receiver board.
As described in the Design section above it will have 3 Grove sensors and 1 Grove LCD display connected to the Arduino MKR Connector Carrier.
a MKR WN 1300 (MKR1) is attached to the Carrier.
one by one, each sensor is read.
- after each sensor is read, a LoRa a packet with the sensor value is sent
- In the packet send function the value is displayed on the LCD display.

Sending Data to the Arduino IoT Cloud

This sketch sends data to the IoT Cloud Dashboard
It runs on the Nano 33 IoT board and connects via a WiFi connection.
The sketch, is Auto Generated when you initially create a thing connected to a device on the Arduino IoT cloud
NOTE: the Nano board script is generated automatically when creating a new Thing on the Arduino IoT cloud as described in the online tutorial
- Getting started with the Arduino IoT Cloud
Here is my Thing on the Arduino Cloud with the variables defined.
The sketch is generated on the sketch Tab as described below.
Here is a screenshot of the sketch generated to send data to the thing that I created on the IoT cloud.

I then added my code to this sketch to receive serial data, parse the packet to extract the value and set the value to the proper variable
The variable is then sent to the Thing and onto the Dashboard.

Here is the entire sketch that will run on the Nano 33 IoT:

/* 
  Sketch generated by the Arduino IoT Cloud Thing "1554H2GYCL "
  https://create.arduino.cc/cloud/things/f6a8d66c-2702-45e7-b93a-a2d41f9bedb8 

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  String water;
  float dust;
  float temp;
  int waterInt;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.

I think I missed the punch line - what was the size limit that you encountered with the code block?

Nice build.

It will be interesting to see how everything works over time.

Thanks for the clarification. I guess we're all still figuring out this new system...

I've been bitten by the moderation bug a few times - makes me afraid to edit something that's already been posted.

It seems to be happening less or maybe I'm doing less.

Hi ralphjy

I'm not sure of the limit on the size of the code blog. I was testing the different sizes of code blogs. The size depends on if your blog goes into moderation or not.

I'm getting frustrated with creating blogs with code blocks that keep getting sent to moderation.and this one did as expected.

The Team releases them in a short time, but it is very frustrating when your editing and posting changes to your code.. What a pain.

Sorry about the confusion
